Classical ray tracing techniques based upon acoustic theory are shown to effectively reproduce pressures measured in tests of linear arrays of bulk charges placed near a sand bottom. It is shown that accurate agreement with measured records rests upon the determination of a bottom reflection coefficient as a function of the problem geometry and other problem-dependent conditions. In the present model, bottom reflection coefficient functions suitable for modeling the results of 1995 Eglin AFB tests are determined empirically. Consequently, the model is not currently suitable for predicting pressures at other test sites.
